Mysteries of My Neighborhood #1

An entry path for humans.... leading to a wall of ivy. Why? Alice wanted to take my picture on the concrete path, but there is something..... didn't want to tarry there.
Nearby is a fancy metal plaque cemented into the ground for a sculpture long gone. I've never seen the sculpture. Alice "says" there was once a carved limestone heart behind these clipped box bushes. I doubt it. I rarely linger over there, too.
